Washington Redskins linebacker Keenan Robinson could miss the entire season with a torn left pectoral muscle, according to NFL Network and the Washington Post.
The 2012 fourth-round draft pick from Texas could miss anywhere from three to five months.
Robinson got hurt Thursday
It's a familiar injury for Robinson, who tore his right pectoral and was out for the season last year as a rookie.
He had to undergo surgery for that one and will likely require another surgery to repair the damage to his left side.
Robinson was regarded as a key backup.
